打印数组的相应值

arr = [1, 2, 3, 4, 5]
for i in range(len(arr)):
    print(f"Element at index {i} is {arr[i]}")

int[] arr = {1, 2, 3, 4, 5};
for (int i = 0; i < arr.length; i++) {
    System.out.println("Element at index " + i + " is " + arr[i]);
}

let arr = [1, 2, 3, 4, 5];
for (let i = 0; i < arr.length; i++) {
    console.log(`Element at index ${i} is ${arr[i]}`);
}

#include <iostream>
using namespace std;

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int n = sizeof(arr) / sizeof(arr[0]);
    for (int i = 0; i < n; i++) {
        cout << "Element at index "<< i << " is " << arr[i] << endl;
    }
    return 0;
}

for i in range(len(arr)):  # 正确
for i in range(10):  # 错误，可能导致索引越界

if len(arr) > 0:
    for i in range(len(arr)):
        print(f"Element at index {i} is {arr[i]}")
else:
    print("Array is empty")
